MODULE 22

Environmental Controls, HVAC & Smart Room Climate

Intelligent, occupancy-aware management of room climate, air quality, and energy consumption. Deeply integrated with the PMS for real-time occupancy data, the system automates setback temperatures, restores guest comfort settings on arrival, and delivers full visibility and control.

Central HVAC Management

Centralized climate control with BMS integration and fault detection.

Centralized HVAC control dashboard for all property zones (rooms, corridors, lobby, F&B, back-of-house, function rooms)

Real-time zone temperature display and trend monitoring

BMS (Building Management System) integration: full two-way interface with Siemens, Honeywell, Johnson Controls, Schneider Electric, and Distech platforms

Chiller plant monitoring: supply/return water temperature, chiller efficiency, energy consumption

Air handling unit (AHU) status: fan speed, damper position, filter status, supply air temperature

Fan coil unit (FCU) status and control per room and zone

VRF / VRV system monitoring and zone control

Fresh air and ventilation rate monitoring (CO2 levels per zone)

Humidity monitoring and dehumidification control

Building-wide temperature setpoint management by zone and time schedule

HVAC energy consumption monitoring with efficiency KPIs (COP, EER, kWh/ton)

Fault detection and diagnostics (FDD): AI identifies HVAC anomalies before failure

Filter change alerts based on differential pressure and runtime hours

Refrigerant leak detection integration

Chiller sequencing optimization for multi-chiller plants

Demand-controlled ventilation based on CO2 and occupancy sensors

Free cooling economizer mode management (when outside air conditions allow)

Guest Room Climate Control

Smart thermostat integration with guest preference recall and multi-interface control.

Individual guest room thermostat control (smart thermostat per room: Ecobee, Nest, Honeywell, Inncom, Telkonet, GreenMind)

PMS-integrated occupancy-based setback: room automatically shifts to energy-saving setback temperature when vacant or checked out

Pre-arrival conditioning: room automatically reaches guest's preferred temperature before check-in time

Guest preferred temperature recall from profile — room set to preference on arrival without asking

In-room thermostat UI: intuitive guest interface with temperature set, fan speed, and mode selection

Bedside panel integration: temperature and fan speed control at the nightstand

Smart TV climate control: guest adjusts temperature from in-room TV menu

Guest app climate control: remote temperature adjustment from smartphone before and during stay

Voice control integration: 'Hey Google, set the temperature to 72 degrees' / Alexa in-room control

Occupancy sensor integration: room enters setback mode 30 minutes after vacancy detected

Balcony door / window open detection: HVAC automatically suspends cooling or heating when door open to prevent energy waste

Key card master switch integration: HVAC enters setback mode when key card is removed

Maximum and minimum temperature limits: guest cannot set room below 65°F or above 82°F (configurable per property policy)

Separate zone control for suite living areas and bedrooms

Do Not Disturb integration: setback temperature adjustments suspended while DND active

Guest opt-in for sustainability mode: voluntary higher setback temperature with eco-incentive reward

Engineering override: remote temperature set and override from maintenance dashboard for repair situations

Setback & Energy Optimization

Intelligent pre-conditioning and energy savings management.

Configurable setback temperature profiles: Vacant Dirty, Vacant Clean, Occupied, Checked Out, Out of Order

Time-to-conditioning calculation: system knows how long it takes each room to reach comfort from setback

Intelligent pre-cooling / pre-heating: room reaches guest temperature exactly at check-in, not an hour early

Occupancy forecast integration: pre-condition rooms based on arrival list from PMS the night before

Seasonal setback adjustment: different setback bands in summer vs. winter

Energy savings reporting: kWh saved per day, per month, per year through setback management

Cost avoidance dashboard: dollar value of HVAC energy saved through occupancy-linked control

Peak demand curtailment: temporarily raise setback temperatures property-wide during utility peak demand windows

Room-level energy benchmarking: identify rooms consuming significantly more energy than floor average

Guest impact analysis: measure guest satisfaction score correlation with temperature complaint rates

LEED and Green Globe energy reporting: automated generation of data required for sustainability certification

Carbon reduction reporting: tonnes of CO2 equivalent saved through HVAC optimization

Air Quality, Water & Additional Environmental Controls

Air quality monitoring, water management, and environmental compliance.

CO2 monitoring per guest room and public area with alert thresholds

VOC (Volatile Organic Compound) and particulate matter (PM2.5) air quality monitoring

Air quality dashboard with color-coded zone health indicators

Automatic ventilation rate increase triggered by CO2 threshold breach

In-room air purifier integration: monitoring and filter status tracking

Bathroom exhaust fan automation linked to occupancy sensor

Hot water system temperature monitoring (Legionella prevention: circulation loop above 60°C / 140°F)

Legionella management: automated flushing schedule for infrequently used outlets with compliance log

Domestic cold water temperature monitoring for health regulation compliance

Pool and spa water chemistry monitoring: pH, chlorine, ORP, temperature, and turbidity

Pool chemistry alert and automated chemical dosing system integration

Irrigation system scheduling with soil moisture sensor integration

Rainwater harvesting system monitoring (tank levels, pump status, usage tracking)

Noise monitoring in guest corridors and public areas with alert thresholds

Smoke detector, CO detector, and fire suppression system status monitoring across all zones

Environmental compliance reporting for regulatory and certification submissions
